Patent CA-1287821-C (CA)
Title: Formulating pasty materials
Inventor: DOWZALL MARTIN E
IPC: C09D7/80
Filed: 1986-05-14
Granted: 1991-08-20
Abstract: ABSTRACT OF DISCLOSURE      Two or more pasty materials may be accurately formulated together by sequentially extruding the desired amounts of those materials into a tube (5) with graduations (7) associated with it to measure the amounts extruded.  After the components have been put serially into the tube (5), they are removed from the tube, e.g. by squeezing the tube and moving the squeeze towards one end and mixed to homogeneity.  Preferably the mixing takes place in a container on to which a lid may be put and from which the mixture may then be extruded, e.g. by having a movable base on the container which then acts as a piston to extrude the mixed formulated paste through a nozzle in the lid.

Abstract: Curved, Uniformly Biased Structural Fiber Forms Abstract A process for forming a dry fiber form susceptible of being infused with a resin and molded to a fiber reinforced plastic structural article, wherein the fiber form is comprised of a structural fabric bearing plys of biased yarns, the bias of the yarns being maintained along the curvature of the fiber form, without wrinkling or buckling of the fiber form.  The structural fabric is attached to a form bearing a shape-defining opening, and threads are sewn within the opening.  The fabric is then removed from the form, and the ends of the fabrics are then sewn with more threads parallel to the first set of threads.  Thereafter, the excess is trimmed away, and the resulting sewn fiber form may be infused with resin and molded into a structural article.

Granted: 1991-02-05
Abstract: ABSTRACT OF THE DISCLOSURE      ELECTRICAL CONNECTOR An electrical connector includes stab portions and a cam for urging a wire cord into contact therewith. The cam mounts in a tubular housing which is telescopically receivable in a sleeve. The cam and housing coact such that the cam head tends to move outwardly from the housing when the cam is moved to a position to release the wire cord, and this is prevented by the sleeve. As a corollary, if the cam is turned away from its wire locking position, the housing cannot be engaged with the sleeve. The sleeve acts as a conduit for the wire cord, whereby the cord tends to anchor the housing in telescoped position in the sleeve, to prevent unauthorized tampering with the connector.

Title: Memory arbitration for video subsystem
Inventor: THOMPSON STEPHEN P
IPC: G09G1/16
Filed: 1988-02-04
Granted: 1992-03-17
Abstract: Abstract A video subsystem has a CRT display, video controller and video memory for CRT data which requires access by the controller and a CPU.  The subsystem monitors activity of the CRT screen display and the video controller and anytime CRT screen display is not required regardless of the time of occurrence, the CPU is allowed to have access to the video memory during the cycle or cycles in which such inactivity of display occurs.      A guaranteed minimum number of cycles is assured for access of the video memory by the CPU during a high speed mode, but in addition arbitration allows CPU access to occur during non-display times so that the CPU can acquire more cycles if necessary.  In a low speed mode, arbitration occurs both during display and non-display periods so that the CPU can acquire memory cycles on an as needed basis.

Title: Removal of deleterious odor-forming impurities from hop flavors
Inventor: TODD PAUL H JR
IPC: A23L27/12
Filed: 1988-03-31
Granted: 1995-07-04
Abstract: A novel method for the removal of hitherto un-recognized undesirable odor-forming impurities from hop flavors, including unreduced alpha and isoalpha acids and reduced alpha and isoalpha acids, by extracting the impurities from these flavors into water at a pH above 4, preferably above 6 or 7, with or without the presence of salt or solvent, and separating the aqueous phase containing the impurities from the purified hop flavor, as well as the important two-phase and salt-containing intermediate products and the final purified hop flavor which is essentially free of such impurities and which purified isoalpha acid or isohumulone will therefore not produce fruity, estery, sour aromas when used to flavor beverages,  e.g., beer or ale,  are disclosed.  A rapid test for the detection of such aromas, involving dissolution of the hop flavor in ethanol at a concentration of one-half percent w/v and allowing the solution to stand for four days, allows  accelerated determination of the presence or absence of such aromas and the odor-forming impurities which cause the undesirable odors.

Granted: 1991-11-26
Abstract: TIME-VARYING TRELLIS-CODED MODULATION FORMATS    WHICH ARE ROBUST IN CHANNELS WITH PHASE VARIATIONS           Abstract There are described apparatus and methods for producing time-varying of trellis-coded modulations, specifically, time-varying trellis-coded phase-shift-keying, to facilitate carrier phase recovery when the signal has been exposed to extraneous phase variations and noise.           Typically, eight-phase-shift-keying (8-PSK), with rate 2/3 convolutional coding, is followed on a repetitive basis by one or two formats of four-phase-shift-keying (4-PSK), which formats are chosen to ease phase synchronization and to conserve the use of bandwidth and not to worsen the bit error probability while reducing the probability of synchronization loss and the length of error bursts or "random walks".          The variation of the modulation formats could be: 1) 8-PSK (rate 2/3) followed by 4-PSK, 2) 8-PSK (rate 2/3) followed by 4-PSK (preferred format) and then 4-PSK      (secondary format) or, 3) any of many other periodic formats of 8-PSK and 4-PSK sections. The use of this improved type of modulation is contemplated, for example, mobile radio links, particularly to counteract fading, or for optical fiber links to counteract other causes of signal degradation.
